Duh, I turned on my brain and buzzed out the connector to the PC board.
  If I number the connectors like this

            +-------+
            | 1 2 3 |
            +-------+
            | 4 5 |
            +-------+

Then 2, 4, 5 = GND, 3 = +5V regulated, 1 is > +12V unregulated.

That is, pin 1 goes to a 7812 regulator, pin 3 goes directly to +5 on
the digital logic, and the other three are grounds.

I've gotten so used to quickly finding things with google I forgot some
of the old fashioned techniques -- like figuring it out myself.
